An input widget for Yii 2.0 widget based on the yii2-sortable extension that allows you to create sortable-input lists and grids and manipulate them
using simple drag and drop. It extends the yii2-sortable features by allowing you to store the sort order in a form input (which is hidden by default). The widget stores the order as
delimited list item keys. The widget includes additional jQuery enhancements to initialize the list, trap sortable order change, and reset order on form reset.

Note: This extension depends on the kartik-v/yii2-sortable extension which in turn depends on the kartik-v/yii2-widgets and
yiisoft/yii2-bootstrap extensions. Check the
composer.json for this extension's requirements and dependencies. Note: Yii 2 framework is still in active development, and until a fully stable Yii2 release, your core yii2-bootstrap packages (and its dependencies)
may be updated when you install or update this extension. You may need to lock your composer package versions for your specific app, and test
for extension break if you do not wish to auto update dependencies.
